Using tea leaves to make quantum dots is both cheap and non-toxic

We might be one step closer to defeating lung cancer thanks to an interesting discovery involving tea leaves. A collaboration between researchers from India and from Swansea University have discovered certain nanoparticles derived from these leaves can slow down the growth of cancer cells in the lung and even destroy up to 80 percent of them. This discovery is truly remarkable and might highlight a bright future for cancer research.

Researchers produced quantum dots from tea leaves

The research team was experimenting with the nanoparticles in question, which also bear the name of quantum dots. This name comes from their incredibly small size, as they are thinner even than a strand of hair. These particles have been studied in depth only recently, as researchers found out they have an application not only in technology, but also in healthcare.

However, what is even more interesting about these quantum dots is their origin. They can be produced through some chemical reactions, but the process isn’t too easy. Moreover, it consumes a lot of resources and might even be dangerous. Fortunately, researchers found a new method to obtain them.

By using extract from tea leaves, they were able to produce these quantum dots. Tea leaves are perfect for the process, as they contain plenty of beneficial substances, like antioxidants or amino acids. After using extract from the tea leaves, they mixed it with two other chemical substances. The reaction between them later formed quantum dots.

The nanodots could destroy 80 percent of lung cancer cells

Afterwards, they tested these quantum dots on lung cancer cells and were astonished to observe their effect. The nanoparticles of the dots flowed through the pores of the cancer cells and managed to inhibit their growth. Easily, they destroyed about 80 percent of the cells, which is definitely remarkable.

Both findings came as a surprise and a great achievement. Producing quantum dots from tea leaves is a lot cheaper and less toxic, which makes for a non-expensive and possibly more effective treatment against lung cancer.

The study in question was published in the journal Applied Nano Materials.
